National Center of Scientific Research “Demokritos”, Greece

Margaritis Gjoka obtained a Ph.D. degree in condensed matter physics from the Ioannina University, Greece, 1999 and an M.S. degree in material science from the Tirana University, 1985. Gjoka was a Lecturer at the “A. Xhuvani” University, Elbasan, Albania, 1985–1992 and has been a Research Scientist at the NCSR “Demokritos”, since 1995. Gjoka's current research is measurement of the magnetic properties of ITER vacuum vessel materials and welds, NdFeB magnets, and hard magnets. His activity is focused on the composition, characterization, and study of new hard magnetic and nanostructured materials, high temperature magnets, nanocomposite magnets and their applications in the nanotechnology, hydrogen storage, and fuel cell for energy applications. It has published 50 papers in the scientific periodicals with refereeing, 17 others in the proceeding of international conferences, and 22 in the proceeding of Greek conferences, in total 46 presentations at the international conferences; citations 410. Gjoka's specialization is as follows: (i) main field: magnetic materials, investigation of new magnetic materials and (ii) other fields: solid state physics, structure characterization: X-ray and neutron diffraction, physical metallurgy, Mossbauer analysis, nanocomposites, nano. Gjoka received the Scholarship of UNRSCO, Laboratory of Mineralogy-Crystallography, Paris 6, 1985 and is a Member of the Hellenic Society of Science and Technology of Condensed Matter.
